Application filed June 28, 1908. Serial No. 189,918.

, tion in detail it'may be employed in the con struction of hames ofother types.

In the accom anying drawings, Figure I is a view in si e elevation of ahame, the portion of the filler shell within the main shell beingindicated in line. Fig. II is a view 0 the same, in ed e elevation, siht being taken t ward'the rig t hand side 0 the structure of Fig. I.Fig. III is a longitudinal sectional elevation on the line III--III ofFig. II. -Figs. IV, V,

VI, and VII are sectional elevations of the structure, sections being suposed taken for the res tive figures on t e lines IV-IV,

V-V, --VI, and VII-VII, respectively.

Similar letters of reference indicate corresponding arts.

The y of my improved hame is in the preferred embodiment of my inventionillus trated in the above mentioned drawings produced by the union oftwo metal shells each trough gutter or U-shaped in transverse section.one of which I term the main shell, a, the other the filler shell, d,arranged with their concavities' in opposition and with the side wallsof the one extended between and in'lateral contact with those of theother. In. the arrangement depicted the walls of'theoneshell overlie soto speak those of theother, so that the wall edges of thefone shell areout of registry'with the wall edges of the other.

In practice the shells, which are preferably made of steel, maybeconveniently stamped by dies or hammered :Eromv suitably flat stris intothe axial conformation and tron -sha section required.

she embodies the usual outwardinward axial curves at its a r and ershell profile by a dotted filler shell is design embodies an axialinward curve at its lower end.

The curved axial line of the com leted hame is in a' plane which is inparal elism with the side walls of the shells at the central part of theheme, and, as seen in Fig. I, the basal portion of the filler shellforms the concave or inner face and the basal portion of the main shellthe convex or outer face of the curved region in the lower-part of the,hame. While both of the shells areof a' general trough or U-shape' intransverse section, each, in the preferred embodiment illustrated, has aspecial further conformation, as follows: The body of the main shell isfor a suitable distance as to its basal wall flat from edge to edge,that is to say, in

transverse'section said wall exists in a plane at a right an 1e with resect to the side walls 6, c, of t e said shel and Said basal wall is inthe assemblage of the shells encountered by the edges of the side walls,6, f, of the filler shell, d, the contact of said side -walls with saidbasal walk-which latter serves so tospeakas astop for thefillershell,-maintaming the parts in position against displacement by externalpressure on the base of either shell.

The filler shell in transverse section is as to one wall, e, aproximately straight from edge tobase, an as to'the other, 7, straightas to its outer 'onedge re ion and in substantial parallelism with saiwall e and curved as to its basal region, so that it externallyapproximates the form of the wooden filler b ocks hitherto em loyed, andwhich the e to replace; Both walls of the filler shell 'raduallyincrease in height from their en s toward their central portions, asshown more particularly in Fig. I. The shanks of a staple, g, a bolt, h,the outer end of which carries a line ring, '2', and one shank of astaple, j, extend as rivets through both shells, and being upset attheir inner ends, secure the shell members firmly together, reinforcingthe hold of the main shell-upon thefiller shell. f

The opposinqedges of the end regionsof the mainshell as distinguishedfrom the body region are brou ht together as shown in Fig. IIi so thatsaid end regions areapmain shell to supportthe eye below said" shell.

'Aswill be observed, especially from Figs.

I IV, and VII theside'wall c of the main shell is, where the arrangementand proportions of the parts permit, bent as to lts outer edge slightlyinward'to follow the conformation of the curved Wall of the fillershell.

The shells are :--;i'a1n1'=ed out with great.

rapidity, and, being shaped in forming dies,

the desired COnfigLH'fitlC-ll may be imparted with accuracy, and the-ormed shells quickly and easily assembled. The completed structure isstrong and durable even though comparativelythin metal be used inmaking. it.

In the preferred embodiment of vmy invention illustrated, the walls ofthe main shell are,'inthe region of the deeper portion of the hame, forexample the region between the section lines VV and VI-VI of Fig. 7

I, in transverse section, approximately parallel and perpendicular tothe base ot said shell, and also, in the same region, the portions ofthe walls of the filler shell in the vicinity of the outer edges of saidwalls (being the edges which are in the assembled position of the partsadjacent to the base of the main shell)*are, in transverse section,approximately parallelism with each other and with the walls of the mainshell which their side. faces confront or oppose;

at points in the vicinity of the ends howeverthe sidewalls of the mainshell gradually merge into the substantially annular form of said ends.lVhen in the claims I referto walls as being straight or flat, it willbe understood that the phraseology covers such reasonable variationtromflmathematical accuracy as the form of the heme manufactured andconvenienceot manufacture may dictate.

Having thus claim and desire to secure by Letters Patent:

1. A metal filler shell for-a hame, approximately trough shaped intransverse section and having side walls of-tubstantially equal heightone wall being substantially; straight from-edge to base and the othercurved as toitsbase. .i

2. A metal filler shelljtor-a l1ame,-the same-being approximately troughshaped in transverse section and having side walls of substantially thesame height one wall being approximately straightfromfedge tobasedescribed my invention, l.

.3 A hame comprising amen main shell, having suitably arranged endregions and a central body which is approximately trough shapedinsection, and a hollow metal filler, shell arranged within said centralbody and extending substantially from end to end thereof, with theexterior faces of the side bases of the same. i

5. A hame comprising a metal main shell having suitably arranged endregions and central body which is of approximately trough shaped crosssection, and' a hollow metal iiller shell arranged within said centralbody and extending substantially from .end to end thereof, with theexterior faces oi the side Walls of said filler shell opposing the innerfaces of thewalls of the main shell, said central body havinga curvaturein its length the basal portions of the respective shells constitutingthe respective faces of such curved convex and concave portion.

6. A a main shell and a filler shell, both of metal,

hamethebody of which is formed elf I and approximately trough shaped intransverse section, arranged and secured with of'thetwo shells mutuallyoverlapping with the edges of the one shell out or registry with theedges of the other. a

7. A hame the hollow central region or body of which comprises'a mainshell and a filler shell, both of metal, and both approximately troughshaped in transverse section, arranged and secured with theireoncavities 1n"opposition,' the side walls'of the filler shell extendingbetween the side wallsof the main shell with theedges of the walls ofthe main shell out of registry with the edges of the walls of the fillershall,
